Venture capital is by far the most interesting form of capital — and, along with tech entrepreneurs, venture capitalists are the most interesting sort of capitalists.

Over the past 60-odd years VCs have propelled Silicon Valley to the heart of the world economy. Now they are driving the rise of artificial intelligence and other clever technologies in China.
